In The Hobbit, Elrond says it was made for the Goblin Wars and is from Gondolin. He mentions it as being a famous blade, but I don't know who used it. I haven't read either of the Book of Lost Tales, yet, so I don't know if that sword is mentioned in either of those.

Hmm. Most likely. I have myself, however, thought that the sword might actually get its power from its wielder, etc Glamdring becomes the sword it is only in the hands of someone who deserves it and so Orcrist per se might not necessarily be a less powerful weapon.
